|
- update to 1.13:
|
|
* Changed the 32-bit Windows build of the library to use the default calling
|
|
convention (cdecl) instead of stdcall, reverting a change from libdeflate 1.4.
|
|
* Fixed a couple macOS compatibility issues with the gzip program.

|
- update to 1.12:
|
|
* Improved CRC-32 performance on short inputs on x86 and ARM.
|
|
* Improved CRC-32 performance on Apple Silicon Macs by using a 12-way pmull
|
|
implementation. Performance on large inputs on M1 is now about 67 GB/s,
|
|
compared to 8 GB/s before, or 31 GB/s with the Apple-provided zlib.
|
|
* Improved CRC-32 performance on some other ARM CPUs by reworking the code so
|
|
that multiple crc32 instructions can be issued in parallel.
|
|
* Improved CRC-32 performance on some x86 CPUs by increasing the stride length
|
|
of the pclmul implementation.
|
|
* Improved Adler-32 performance on some x86 CPUs by optimizing the AVX-2
|
|
implementation. E.g., performance on Zen 1 improved from 19 to 30 GB/s, and
|
|
on Ice Lake from 35 to 41 GB/s (if the AVX-512 implementation is excluded).
|
|
* Removed the AVX-512 implementation of Adler-32 to avoid CPU frequency
|
|
downclocking, and because the AVX-2 implementation was made faster.
|
|
* Improved Adler-32 performance on some ARM CPUs by optimizing the NEON
|
|
* Improved compression performance slightly.
|
|
* Detect arm64 CPU features on Apple platforms, which should improve
|
|
performance in some areas such as CRC-32 computation.
|
|
* The included `gzip` and `gunzip` programs now support the `-q` option.
|
|
* The included `gunzip` program now passes through non-gzip data when both
|
|
the `-f` and `-c` options are used.

|
|
|
|
- update to 1.10:
|
|
* Added an additional check to the decompressor to make it quickly detect
|
|
certain bad inputs and not try to generate an unbounded amount of output.
|
|
* Cleaned up a few things in the compression code.

|
|
|
|
- update to 1.9:
|
|
* Heuristics were implemented which significantly improve the compression
|
|
ratio on data where short matches aren't useful, such as DNA sequencing
|
|
data. This applies to all compression levels, but primarily to levels 1-9.
|
|
* Levels 1 was made much faster, though it often compresses slightly worse
|
|
than before (but still better than zlib).
|
|
* Levels 8-9 were also made faster, though they often compress slightly worse
|
|
than before (but still better than zlib). On some data, levels 8-9 are much
|
|
faster and compress much better than before; this change addressed an issue
|
|
where levels 8-9 did poorly on certain files. The algorithm used by levels
|
|
8-9 is now more similar to that of levels 6-7 than to that of levels 10-12.
|
|
* Levels 2-3, 7, and 10-12 were strengthened slightly.
|
|
* Levels 4-6 were also strengthened slightly, but some of this improvement was
|
|
traded off to speed them up slightly as well.
|
|
* Levels 1-9 had their per-compressor memory usage greatly reduced.
|
|
* `make install` will now install a pkg-config file for libdeflate.
|
|
* The Makefile now supports the `DISABLE_SHARED` parameter to disable building
|
|
the shared library.

|
|
|
|
- update to 1.8:
|
|
* Added `-t` (test) option to `libdeflate-gunzip`.
|
|
* Unaligned access optimizations are now enabled on WebAssembly builds.
|
|
* Fixed a build error when building with the Intel C Compiler (ICC).
|
|
* Fixed a build error when building with uClibc.
|
|
* libdeflate's CI system has switched from Travis CI to GitHub Actions.
|
|
* Made some improvements to test scripts.

|
- Add workaround build fail due issue in dwz by deleting
|
|
libdeflate-gunzip and replace with symlink libdeflate-gzip to
|
|
fix dwz break with hardlink.
